Diagnostics

About Error Messages

A hexadecimal number designates each error message reported by Diagtools; a short note on the type of error; and a list of one or more steps the user can take in response. When you run a test, it exercises many aspects of the hardware, so the number of possible error messages exceeds 300. Most of these are encountered rarely, if ever.

Error codes can be viewed on line from the Diagtools User menu within the advanced series of tests, or you can refer to Chapter 3 of the HP Server Diagtools Error Reference and User Guide.

Advantages and Limitations of Hardware Diagnostics

Off-line diagnostic software is useful in making sure the hardware has been eliminated as the cause for possible Server problems. Such diagnostic tools can easily be shipped with a server, and they are relatively easy to use.

Only experienced personnel knowledgeable of its limitations should use off-line diagnostic software.

Some limitations are:

￿￿Booting the Server from the Startup CD-ROM

￿￿No access to operating system error logs, since the OS is not operating at the same time as the diagnostic tools

￿￿Limited ability to test only a single component at a time

￿￿Inability to indicate problems with wrongly configured Servers or the network
